Employee Directory

Names are auto-resolved to Lark user_ids. Supported names:

Business Rules

1. Boyang is always added as attendee to every calendar event (automatic)
2. Timezone handling: Uses IANA identifiers (e.g., Asia/Singapore, Asia/Shanghai)
3. Time format: Always YYYY-MM-DD HH:MM:SS
4. user_id vs open_id: This skill uses user_id format (e.g., dgg163e1), NOT open_id (e.g., ou_xxx)

Programmatic Usage

import { createEvent, updateEvent, deleteEvent } from './skills/lark-calendar/lib/calendar.mjs';
import { createTask, updateTask, deleteTask } from './skills/lark-calendar/lib/task.mjs';
import { resolveNames } from './skills/lark-calendar/lib/employees.mjs';

// Create event
const result = await createEvent({
  title: 'Team Sync',
  description: 'Weekly standup',
  startTime: '2026-02-03 10:00:00',
  endTime: '2026-02-03 10:30:00',
  attendeeIds: ['dgg163e1', 'gb71g28b'],
  location: 'Zoom',
  timezone: 'Asia/Singapore'
});

// Create task
const task = await createTask({
  title: 'Review document',
  description: 'Q2 planning doc',
  dueTime: '2026-02-05 18:00:00',
  assigneeIds: ['dgg163e1'],
  timezone: 'Asia/Singapore'
});

Lark API Reference

• Calendar Events API
• Calendar Attendees API
• Tasks API

Permissions Required

Ensure your Lark app has these scopes: - calendar:calendar — Read/write calendar ✅ (already enabled) - calendar:calendar:readonly — Read calendar ✅ (already enabled) - task:task:write — Write tasks ⚠️ (needs to be added for task creation) - task:task:read — Read tasks - contact:user.employee_id:readonly — Read user info ✅ (already enabled)

To add permissions: 1. Go to Lark Open Platform 2. Add scopes: task:task:write, contact:contact:readonly (for dynamic employee lookup) 3. Re-publish the app version

Note: Without contact:contact:readonly, the skill uses a static fallback employee list. Update lib/employees.mjs when team changes.

這個 Skill 質量較好，能正常管理飛書日曆和任務。文件寫得非常詳細，命令列引數和示例都很清楚，小白也能快速上手。支援按名字自動查詢員工很方便，還會自動把 Boyang 加入每個會議。不過建立任務後沒有“完成任務”的功能，時間處理在跨夏令時的時候可能不準。建議用正式 SDK 替換手寫 API 封裝以提高穩定性。總體來說是可用的日常工具，但還有完善空間。
